So I have what seems to be the opposite of image persistence. I have two small areas less than a cm big that look like a glare, but are always there except on black. If there is black then it's not there. But if there is any other color there is 2 patches of like bright washout.
Any ideas what this is and how to fix?

I'm not sure if I undertand what do you mean. Can you post some photos?

I have one of those on my Dell 20.1"
Same thing, visible on everything except black :confused:
I believe I got some sort of liquid on there at some point and forgot about it and when I went to clean it off that remained, very possibly not the same problem you are dealing with, but thought I would toss in my 2c.
 
That's not image persistance. It looks like some objects between the film and backlight. What model is it? Is it under warranty?
 
It could be caused by liquid on the screen soaking through to the polariser, disrupting its function and then drying out
The screen materials and the glues soak up water so it is feasible.
 
That, or they're pressure spots. Did you leave something pressing on the back of the machine while the screen was closed, or press on the display itself somehow?
 
Mine is an Alienware Aurora m9700 17" LCD; no longer warranty'd. There could be pressure from when it's in my backpack.
 
I'd agree with Silent-Circuit. Those look like permanent impact spots.

Dust between backlight and polarizer show up similar to these as dark spots. Liquid would cause different shaped stains, but if you press on an LCD it brightens in the area you are pressing on (if pressing hard enough), so it is probably caused by your backpack.

I doubt there is anything you can do about it. Maybe massaging the screen in those areas fairly gently might help, but unlikely.
